How long will a conventional solar energy system last?

Solar cells, also called photovoltaic (PV) cells by scientists, convert sunlight directly into electricity at an atomic level.

Traditional solar cells are made from silicon, are usually flat-plate, and generally are the most efficient.

The basic solar module which is an interconnected, enclosed panel of solar photovoltaic cells, can last more than 30 years.

The best way to ensure and extend the life and effectiveness of your PV system is by making sure it is installed and maintained properly.

Reports from feedback and homeowner complaints indicate that most issues with solar photovoltaic systems arise long term due to improper or sloppy installations.

Solar photovoltaic systems that are designed, installed with no moving parts, and well maintained can last for a long time.

The most important part of the solar photovoltaic systems is the solar panel.

Most solar panels used in home solar arrays come with 25 or 30-year warranties, which means that the solar panels are guaranteed for decades. It’s important to note that the panels will continue to work properly well beyond the end of their warranty period.

As a matter of fact, some earlier designs have been producing electricity daily for about 40 years or so, and are expected to continue powering homes and businesses for decades to come.
